A Holyoke man charged with claiming to be an Uber driver and sexually assaulting a University of Massachusetts student he picked up has been arrested again after allegedly violating bail conditions.

Prosecutors say 18-year-old Samuel Texidor was under house arrest with GPS monitoring after pleading not guilty last month, but left his home over the weekend.

Authorities issued an arrest warrant for Texidor and Holyoke police say he was arrested Monday evening at his home.

Police say Texidor approached a UMass-Amherst student on Sept. 3 and identified himself as a driver for the Uber ride-hailing service. He then allegedly offered the woman a free ride and during the ride assaulted the woman. He denied the charges.
